Problems with returning an article to Takealot.

My husband bought me an air fryer from Takealot as a Christmas present. Unfortunately, when I came to use it, I found it did not have a proper instruction manual. Instead, it had a pamphlet which had very inadequate information. I tried asking my daughter, who has an air fryer, to help, but even she could not get this air fryer to work properly. I ruined two meals trying to use it. I therefore asked my husband to return it for a refund. Takealot came back to us and told us that the air fryer was damaged, which it certainly was not. They then sent it back to us. It is indeed completely undamaged. Ever since, we have been trying to get them to take it back and refund us. They stall and stall and promise to do something about this, but so far nothing has been done. It is now the 21 February, 2023, and this has been going on since December, 2022.
